Disclaimer: I personally do not believe any of this crap. However you did ask what other Christians believe about these scriptures, so here are the quotes from a commonly used Bible Commentary which can be found on this website:

Hebrews 10:25 "not forsake the gathering of ourselves together, as some have the custom, but encouraging one another, and all the more so as you behold the day drawing near."
Matthew Henry Concise Commentary
on the Whole Bible:
Verses 19-25 The apostle having closed the first part of the epistle, the doctrine is applied to practical purposes. As believers had an open way to the presence of God, it became them to use this privilege. The way and means by which Christians enjoy such privileges, is by the blood of Jesus, by the merit of that blood which he offered up as an atoning sacrifice. The agreement of infinite holiness with pardoning mercy, was not clearly understood till the human nature of Christ, the Son of God, was wounded and bruised for our sins. Our way to heaven is by a crucified Saviour; his death is to us the way of life, and to those who believe this, he will be precious. They must draw near to God; it would be contempt of Christ, still to keep at a distance. Their bodies were to be washed with pure water, alluding to the cleansings directed under the law: thus the use of water in baptism, was to remind Christians that their conduct should be pure and holy. While they derived comfort and grace from their reconciled Father to their own souls, they would adorn the doctrine of God their Saviour in all things. Believers are to consider how they can be of service to each other, especially stirring up each other to the more vigorous and abundant exercise of love, and the practice of good works. The communion of saints is a great help and privilege, and a means of stedfastness and perseverance. We should observe the coming of times of trial, and be thereby quickened to greater diligence. There is a trying day coming on all men, the day of our death.

Matthew 28:19,20 "Go therefore and make disciples of people of all the nations, baptizing them in the name of the Father and of the Son and of the holy spirit, teaching them to observe all the things I have commanded you."
Matthew Henry Concise Commentary
on the Whole Bible:
Verses 16-20 This evangelist passes over other appearances of Christ, recorded by Luke and John, and hastens to the most solemn; one appointed before his death, and after his resurrection. All that see the Lord Jesus with an eye of faith, will worship him. Yet the faith of the sincere may be very weak and wavering. But Christ gave such convincing proofs of his resurrection, as made their faith to triumph over doubts. He now solemnly commissioned the apostles and his ministers to go forth among all nations. The salvation they were to preach, is a common salvation; whoever will, let him come, and take the benefit; all are welcome to Christ Jesus. Christianity is the religion of a sinner who applies for salvation from deserved wrath and from sin; he applies to the mercy of the Father, through the atonement of the incarnate Son, and by the sanctification of the Holy Spirit, and gives up himself to be the worshipper and servant of God, as the Father, Son, and Holy Ghost, three Persons but one God, in all his ordinances and commandments. Baptism is an outward sign of that inward washing, or sanctification of the Spirit, which seals and evidences the believer's justification. Let us examine ourselves, whether we really possess the inward and spiritual grace of a death unto sin, and a new birth unto righteousness, by which those who were the children of wrath become the children of God. Believers shall have the constant presence of their Lord always; all days, every day. There is no day, no hour of the day, in which our Lord Jesus is not present with his churches and with his ministers; if there were, in that day, that hour, they would be undone. The God of Israel, the Saviour, is sometimes a God that hideth himself, but never a God at a distance. To these precious words Amen is added. Even so, Lord Jesus, be thou with us and all thy people; cause thy face to shine upon us, that thy way may be known upon earth, thy saving health among all nations.

Matthew 24:45 "Who really is the faithful and discreet slae whom his master appointed over his domestics, to give them their food at the proper time?"
Matthew Henry Concise Commentary
on the Whole Bible:
Verses 42-51 To watch for Christ's coming, is to maintain that temper of mind which we would be willing that our Lord should find us in. We know we have but a little time to live, we cannot know that we have a long time to live; much less do we know the time fixed for the judgment. Our Lord's coming will be happy to those that shall be found ready, but very dreadful to those that are not. If a man, professing to be the servant of Christ, be an unbeliever, covetous, ambitious, or a lover of pleasure, he will be cut off. Those who choose the world for their portion in this life, will have hell for their portion in the other life. May our Lord, when he cometh, pronounce us blessed, and present us to the Father, washed in his blood, purified by his Spirit, and fit to be partakers of the inheritance of the saints in light.

the problem I see in using any of this to argue with a JW is that JWs WANT to be special, NEED to be the ONE AND ONLY TRUE BELIEVERS and therefore will not be able to fathom that all the rest of Christianity does not count these particualr scriptures of any more significance than most other scriptures. It is kinda like opening someone's refrigerator and pulling out a half empty jar of sweet pickles and on the basis of that 'proof' accusing them of having a bizarre eating disorder that compulsively craves sweet pickles.... you can pick any scripture at random and create a whole new religion based on it if you can convince your 'followers' that it is a a unique scripture that applies only to them and that God himself speaks thru you and said that no one else but them can possibly understand it---ooooo aren't we special?
just remember the first thing you need to reason with someone is someone who is capable of reason and rational thought.
